Soonfire FD38S bright bike light

The FD38S model bike light from Soonfire has a lumen output of 1870 on the highest setting, with 5 different brightness settings to toggle between. There is also a strobe function for alerting motorists about your presence, and an SOS function for emergencies. The light runs on a built-in battery pack, consisting of 2 x 18650 batteries that are rechargeable with the included USB cable, plugged straight into the light. The runtime on the Soonfire FD38S is quite impressive too, on the highest setting the light will last for 4.5 hours. That, combined with a fair price and great user reviews of 4.6 out of 5 puts it on our list of the top bike lights.

The FD38S uses two Cree LED bulbs to emit its super bright white light with brightness outputs ranging from 15 to 1870 lumens. You can’t remove the batteries to insert charged spare ones, as this one uses a built-in battery pack, but with a 4.5 hour runtime on the highest setting, you probably wouldn’t need to anyway. IP67 water-resistant rating lets you use the bike light in any weather conditions as well. The shape on this thing is nice too, if you need a flashlight you can just use the FD38S for that as well, as it doesn’t have the standard bulky bike light design that the majority of other lights have. Easy to clip on and off the handlebar as well
